History and Lore
Ancient Beliefs and Royal Associations
Sapphires have a rich historical legacy, with their use dating back to ancient civilizations. In ancient Greece and Rome, blue sapphires were believed to protect their owners from harm and envy. These gemstones were often worn by the elite, who associated them with wisdom, truth, and nobility. The clergy of the Middle Ages also revered sapphires, seeing them as symbols of Heaven and incorporating them into their attire and rituals.
One of the most fascinating historical beliefs about sapphires comes from ancient Persia. The Persians believed that the earth rested on a giant sapphire, which gave the sky its blue color. This belief underscores the cultural significance of sapphires and their perceived connection to the cosmos.
During the Middle Ages, sapphires were thought to have healing properties. Medieval Europeans believed that sapphires could cure plague boils and diseases of the eye. They were also considered an antidote to poison, further cementing their role as protective talismans. These beliefs, while not scientifically substantiated, reflect the deep cultural and symbolic meanings attributed to sapphires.
Modern Significance
In modern times, sapphires continue to hold a special place in both jewelry and cultural traditions. They are the designated birthstone for September and are also the gemstone that commemorates the 5th and 45th wedding anniversaries. The association of sapphires with these milestones highlights their enduring value and the trust placed in their symbolic meanings.
Famous sapphires, such as the Rockefeller Sapphire and the sapphire engagement ring worn by Princess Diana and later by Kate Middleton, further illustrate their prominence in contemporary culture. The Rockefeller Sapphire, a 62.02-carat rectangular step cut stone, was discovered in Myanmar (Burma) and has a storied history of ownership and transformation. The sapphire engagement ring, on the other hand, has become an iconic symbol of royal romance and is a testament to the gemstone's lasting appeal.
Geological Formation and Sources
The Corundum Family
Sapphires belong to the corundum family, which is composed of aluminum oxide (Al₂O₃). The term "sapphire" typically refers to the blue variety of corundum, while the red variety is classified as a ruby. The color of a sapphire is primarily due to trace amounts of elements such as titanium and iron. When these elements are present in the right proportions, they create the characteristic blue hue that sapphires are known for.
Sapphires can also be found in a range of other colors, including violet, purple, green, pink, yellow, grey, black, brown, and even clear. These variations are referred to as "fancy color" sapphires and are highly valued for their rarity and uniqueness. The absence of silicon in the formation process is a key factor that contributes to the rarity of sapphires. Unlike many other gemstones, sapphires cannot form when silicon is present, making their creation a rare and special event.
Key Mining Locations
Historically, some of the most prized sapphires have come from specific regions known for their high-quality deposits. Kashmir, Myanmar (formerly Burma), and Sri Lanka are three of the most notable sources. Each of these locations produces sapphires with distinct characteristics that set them apart in the gemstone market.
Kashmir is particularly famous for producing sapphires with a unique cornflower blue color and a velvety sheen. These sapphires are highly sought after and command premium prices. Myanmar, on the other hand, has a long history of sapphire mining, with the country being one of the primary sources of the gemstone for centuries. Sri Lankan sapphires are also well-regarded, known for their clarity and vibrant colors.
In addition to these traditional sources, sapphires have also been found in other parts of the world, including Australia, Thailand, Cambodia, Madagascar, and the United States (Montana). Each of these regions contributes to the global supply of sapphires, ensuring that the gemstone remains accessible to jewelers and collectors alike.
Gemological Properties
Color and Clarity
The most defining feature of a sapphire is its color, with blue being the most well-known and highly valued. However, as mentioned earlier, sapphires can also be found in a variety of other colors. The intensity and purity of the color are critical factors in determining the gemstone's value. A sapphire with a deep, rich blue color is generally more valuable than one with a lighter or more muted hue.
Clarity is another important aspect of a sapphire's quality. High-quality sapphires are those with few visible inclusions or blemishes. These inclusions are natural imperfections that occur during the gemstone's formation and can affect its clarity and brilliance. While some inclusions are acceptable and even desirable in certain contexts, an overly included sapphire may be considered less valuable. The clarity of a sapphire is typically assessed using the same criteria as diamonds, with terms such as "eye-clean" indicating that the inclusions are not visible to the naked eye.
Cut and Carat
The cut of a sapphire plays a crucial role in its overall appearance and value. A well-cut sapphire will maximize its brilliance and color, while a poorly cut stone may appear dull or lifeless. The most common cuts for sapphires include the round brilliant, oval, cushion, and emerald cuts. Each cut is designed to enhance the gemstone's natural beauty and optimize its light return.
Carat weight is another factor that influences the price of a sapphire. Larger sapphires are rarer and, therefore, more expensive. However, the carat weight should be balanced with other factors such as color, clarity, and cut. A large sapphire with a poor color or clarity grade may be less valuable than a smaller sapphire with superior characteristics.
Hardness and Durability
Sapphires are known for their exceptional hardness and durability, which makes them ideal for everyday wear. On the Mohs scale of mineral hardness, sapphires rank at 9, second only to diamonds, which rank at 10. This high hardness means that sapphires are resistant to scratches and abrasions, making them a durable choice for jewelry.
In addition to their hardness, sapphires also have good toughness, which refers to their ability to resist breakage or chipping. While sapphires are generally tough, they can be susceptible to chipping if struck at a weak point, such as a corner or edge. Proper care and handling are essential to preserving the integrity of a sapphire.
Symbolism and Metaphysical Beliefs
Cultural Significance
Sapphires have long been associated with a range of symbolic meanings, many of which are rooted in their historical and cultural contexts. In ancient times, sapphires were believed to bring protection, wisdom, and good fortune to their wearers. These beliefs have persisted in various forms across different cultures and time periods.
In many Western traditions, sapphires are associated with loyalty, faithfulness, and sincerity. They are often given as gifts to symbolize enduring love and commitment. The association of sapphires with the 5th and 45th wedding anniversaries further reinforces their role as symbols of long-lasting relationships.
In Eastern cultures, sapphires are also highly valued for their symbolic meanings. In India, for example, sapphires are considered to be powerful gemstones that can bring success and prosperity. They are often worn by individuals seeking to enhance their spiritual growth and connection to the divine.
Metaphysical Properties
Beyond their cultural significance, sapphires are also believed to have metaphysical properties that can influence the wearer's well-being. In the realm of crystal healing, sapphires are associated with the throat chakra, which is believed to govern communication and self-expression. Wearing a sapphire is thought to enhance one's ability to communicate clearly and confidently, making it a popular choice for those in professions that require strong verbal skills.
Sapphires are also believed to promote mental clarity and focus. They are said to help calm the mind, reduce stress, and improve concentration. This makes them particularly useful for individuals who need to maintain a clear and focused mindset, whether in academic, professional, or personal settings.
In addition to their cognitive benefits, sapphires are also associated with emotional healing. They are believed to help individuals process emotions, overcome fears, and build self-confidence. Wearing a sapphire is thought to encourage a sense of inner strength and resilience, enabling the wearer to navigate life's challenges with greater ease.
Care and Cleaning
Proper Maintenance
Given their durability and hardness, sapphires are relatively easy to care for compared to other gemstones. However, proper maintenance is essential to preserving their beauty and longevity. One of the key considerations in sapphire care is avoiding exposure to harsh chemicals, which can damage the gemstone's surface or setting.
When cleaning a sapphire, it is best to use a gentle solution of warm water and mild dish soap. A soft-bristled brush can be used to gently scrub the gemstone and its setting, removing any dirt or debris. After cleaning, the sapphire should be rinsed thoroughly with warm water and dried with a soft, lint-free cloth.
It is important to note that ultrasonic cleaners and steam cleaners should be used with caution when cleaning sapphires. While these methods can be effective for some gemstones, they may not be suitable for sapphires with certain inclusions or treatments. It is advisable to consult with a professional jeweler before using these cleaning methods to ensure that the sapphire is not at risk of damage.
Storage and Handling
When not being worn, sapphires should be stored in a secure and protective environment. To prevent scratches and abrasions, it is recommended to store sapphires separately from other gemstones, particularly those that are softer on the Mohs scale. A soft pouch or a jewelry box with individual compartments can provide the necessary protection.
Handling sapphires with care is also important to prevent accidental damage. While sapphires are resistant to scratches, they can still chip or crack if subjected to a hard impact. It is advisable to avoid wearing sapphire jewelry during activities that involve physical contact or exposure to rough surfaces.
